Reconvergence?
I have a 3 node RBR750 network. The router is connected to my ISP router (A), one node is at my server rack (B) and the last node is in my office connecting my pcs (C).
I have a ups on the router and ISP gear. This morning, that ups died, taking the Orbi router (A) and ISP gear off line. Naturally that meant no Internet connectivity.
But was odd was that I could not access my servers (B) from my office PC (C). I was always under the impression that everything was meshed, that is A connected to B, B to C and C to A. In this case, A to B and A to C would be down, but B to C should have still been up.
This morning's behavior seems to suggest that the topology is A to B and A to C, but nothing B to C.

IF the UPS died with the Orbi RBR and ISP Router, then this would cut off ties to any connected RBS.

I've never explored what happens to wifi connectivity when the Orbi router is turned off. Switches continue to work, since they are using layer 2 mac address tables to distribute traffic.
The backhaul connection topology depends on the placement of the three nodes. It is not a full mesh, it is a backbone. So one of
- A - B - C
- A - C - B
- B - A - C
Where the router would be "A".
The network map in the Orbi app should show you the toplogy; you can also see this in the attached devices list in the web ui.

I am thinking the servers are connected with ethernet. Is the ethernet connected to the nearby satellite, or is it connected to the router?
